為什么工控界更信任PLC，選擇PLC作為工控的核心部件呢，主要是由于PLC的以下五個(gè)特點(diǎn)：

1. 可靠性高，抗干擾能力強(qiáng)

無觸點(diǎn)控制：故障率少；

硬件措施：屏蔽、濾波、隔離；

軟件措施：故障檢測、信息保護(hù)和恢復(fù)、警戒時(shí) 鐘（死循環(huán)報(bào)警）、程序檢驗(yàn)

2. 使用靈活，通用性強(qiáng)

產(chǎn)品系列化，硬件結(jié)構(gòu)模塊式，可靈活選用；

軟接線邏輯使得PLC能簡單輕松的實(shí)現(xiàn)各種不同的控制任務(wù)，且系統(tǒng)設(shè)計(jì)周期短。

3. 編程方便，易于掌握

     采用與繼電器電路極為相似的梯形圖語言，直觀易懂， SFC 功能圖，使編程更簡單方便。

4. 接口簡單，維護(hù)方便

    可直接與現(xiàn)場強(qiáng)電設(shè)備相連接，接口電路模塊化。

有完善的自診斷及監(jiān)視功能，便于查出故障原因，并迅速處理。

5. 功能完善，性價(jià)比高

     除邏輯控制，定時(shí)計(jì)數(shù)，數(shù)字運(yùn)算外，配合特殊功能模塊還可以實(shí)現(xiàn)點(diǎn)位控制， PID 運(yùn)算，過程控制，數(shù)字控制等功能，還可與上位機(jī)通信，遠(yuǎn)程控制等
